#10623: wp_kses_decode_entities() calls create_function() each time called

--------------------------+-------------------------------------------------
 Every time wp_kses_decode_entities() is called, create_function() is
 called twice.

 wp_kses_decode_entities() is called at least once in most KSES calls and
 once in all clean_url() calls.  This can result in hundreds of
 create_function()s on normal pages and thousands on edge pages.

 All these create_function()s eat up memory, which can, in edge cases,
 cause a fatal memory allocation error.

 Since these create_function() calls are not used to generate actual
 dynamic code, there's no reason they cannot be replaced with hardcoded
 functions.

 Attached.
